This cord is huge compared to 12/3 from Lowes. I mounted them to install on e track, easy to move into the trailer. But the SO is a bit heavy for that even and probably wont get moved around much unless I can cut it down and use it to run the 211.

Don't use it coiled up like that- run it out or loop it in figure 8's on the ground.

Well shorter lengths for me now. Good information. Those cords was meant to hang on the wall of the shop or trailer and only play out what was needed.

I'll have stay aware of anything that will be a heavy load on them and unwrap when that is the case.

I never bought an extension cord on a retractable reel but they sell a lot of them. Surely the instructions don't state to pull the whole thing out.

I bet the cord reel that melted in the pic was way overloaded for a long period and would have probably failed even stretched out, the fact it was on a reel probably greatly reduced the time it took to do so.

Had a waterbed heater cord burn through the wood underneath the mattress and never tripped the breaker nor burn a hole in the rubber water bed.

Household alternating current sets up a weak magnetic field and collapses it 60 times every second. Setting up and collapsing that magnetic field results in heat. A single cord by itself won’t create enough heat to be a problem. However, if you coil the cord so you have multiple strands running together, constructive interference increases the amount of heat generated. Coil a cord enough times, and run enough current through it and you can create enough heat to ignite household furnishings.

Retractable cords are usually used on tools that are not a constant load but if you were to connect a heater or high wattage worklight you do risk overloading the cord.

For Hardrock- he also wants to pretty much run the 12/3 right at it's limit, if not over iffin' he runs his MM211 on it @ 150amps.
